Why Node
Created Monday 12 July 2021
We will not be using much of Node.js directly, but it is what runs the show.
Node.js is a JS runtime environment, allowing the execution of JS in environments that are not browsers. It elevates JS from a client side language to a ubiquitous language.
[Node.js](https://nodejs.org/en/)
Node is similar in terms of operation to the JRE, and enables use of JS on client and server side.
Nodejs enabled frontend frameworks: Angular, React etc
Nodejs enabled backend frameworks: Express.js, Meteorjs
Nodejs enabled database frameworks: MongoDB
Nodejs enabled realtime communication framework: Socket.io
and many more!
Node may not be strictly necessary for Angular development, but it streamlines the entire process and saves hundreds of hours of development time over the course of a standard project.
- Most of the Angular packages or libraries are distributed as different NPM packages.
- Node allows for automatic translation of Angular projects to browser-compatible HTML + JS + CSS format
- Node provides an environment to run the Angular CLI to automate creation, bootstrapping, builds and deployment of Angular projects.
- Any additional functionality we need can be added through NPM's huge ecosystem of JavaScript-based packages. examples:
- Testing
- Minification
- Encryption
- Styling

95 That may seem like overkill in a simple expression, but suppose you’re trying to convey the expression to a friend over the phone. If you say “factorial of three times factorial of two plus two plus ﬁve” you might mean any of these: Wouldn’t it be better to say, “Add two and two, take the factorial of that, add ﬁve to that, multiply three by that, and take the factorial of the result”? We can do a similar reordering of an expression if we ﬁrst deﬁne versions of all the reporters that take their continuation as an explicit input. In the following picture, notice that the new blocks are commands, not reporters. We can check that these blocks give the results we want:


[gecode-users] Reified Constraints do not propagate
Guido Tack

This is a current shortcoming of the minimodel library. For some linear constraints (such as x==5 in this case) the IntConLevel is ignored. To get the full propagation, you have to post the constraint directly, like this:
Gecode::rel(*test, test->x_[1], IRT_EQ, 5, test->b_[1], ICL_DOM);
Cheers,
Guido

The timebox and habits techniques I tried were using toggle and the pomodoro technique. I also really liked the resource about counterintuitive ways to be productive. I am very much a 'seasons' person - I have had times of great productivity but then I have needed to take time out to reboot. In saying that I am organised and committed - necessity is often a great motivator. Knowing I have a heap of work due helps me stay productive. I also use a series of planning notepads that I refresh on a daily, weekly and monthly basis.
I found the pomodoro technique interesting. 25 minutes seems too short to get anything meaningful done. I think for me sitting in an uncomfortable chair is a good way to make sure I take regular mini breaks. I am quite sensitive to sound so an alarm throws me too much I think.
I think just accepting my natural rhythms was the most useful piece of advice in the resources. I think we spend too much energy fighting with ourselves (and then needing to self medicate to survive). Being in tune with yourself is the best way to be.
I will experiment more with starting small. I, like most people, intimidate myself by trying to make too much progress at once. By planning to make little changes each day (e.g. typing for half an hour every working morning at 9am) is a good way to tackle the things I am scared of.

Mysterious For
问题描述 :
This special program was called "Mysterious For", it was written in C++ language, and contain several simple for-loop instructions as many other programs. As an ACMer, you will often write some for-loop instructions like which is listed below when you are taking an ACM contest.
for (int i = 0; i < n; i++) {
for (int j = i; j < n; j++) {
for (int k = j; k < n; k++) {
blahblahblah();
}
}
}
Now, MatRush has designed m for-loop instructions in the "Mysterious For" program, and each for-loop variable was stored in an array a[], whose length is m.
The variable i represents a for-loop instructions is the i-th instruction of the "Mysterious For" program.There only two type of for-loop instructions will occur in MatRush’s "Mysterious For" program:
1-type: if a for-loop belongs to 1-type, it will be an instruction like this:
for (int a[i] = 0; a[i] < n; a[i]++) {
…
}
2-type: if a for-loop belongs to 2-type, it will be an instruction like this:
for (int a[i] = a[i - 1]; a[i] < n; a[i]++) {
…
}
In addition, after the deepest for-loop instruction there will be a function called HopeYouCanACIt(), here is what’s inside:
void HopeYouCanACIt() {
puts("Bazinga!");
}
So, the "Mysterious For" program, obviously, will only print some line of the saying: "Bazinga!", as it designed for.
For example, we can assume that n equals to 3, and if the program has three 1-type for-loop instructions, then it will run 33=27 times of the function HopeYouCanACIt(), so you will get 27 "Bazinga!" in total. But if the program has one 1-type for-loop instruction followed by two 2-type for-loop instructions, then it will run 3+2+1+2+1+1=10 times of that function, so there will be 10 "Bazinga!" on the screen.
Now MatRush has the loop length n and m loop instructions with certain type, then he want to know how many "Bazinga!" will appear on the screen, can you help him? The answer is too big sometimes, so you just only to tell him the answer mod his QQ number:364875103.
All for-loop instructions are surely nested. Besides, MatRush guaranteed that the first one belongs to the 1-type. That is to say, you can make sure that this program is always valid and finite. There are at most 15 1-type for-loop instructions in each program.
输入:
For every case, there are 2 lines.
The first line is two integer n(1<=n<=1000000) and m(1<=m<=100000) as described above.
The second line first comes an integer k(1<=k<=15), represents the number of 1-type loop instructions, then follows k distinctive numbers, each number is the i-th 1-type loop instruction’s index(started from 0), you can assume the first one of this k numbers is 0 and all numbers are ascending.
All none 1-type loop instructions of these m one belongs to 2-type.

Every domain name is within a TLD, or top-level domain. This page lists some of the quirks Mail-in-a-Box users have found in TLDs that might impact whether you can successfully set up Mail-in-a-Box.
The following TLDs have worked for us:
These TLDs are working except possibly for setting up DNSSEC. While DNSSEC is optional, it is a neat security protection to have.
Not yet known if DNSSEC is working:
Known to have DNSSEC problems:
These TLDs require two distinct nameservers, which requires a more complex setup. Avoid these if you can or be prepared to host your own DNS or find a secondary DNS service.
For other TLDs, unfortunately we don’t yet know.
If you will register your domain name with Gandi, check their list of TLDs that support DNSSEC. DNSSEC is optional on Mail-in-a-Box, but it’s nice to have.
Please submit a patch by forking this repository if you find anything out.


Notes on Regression and Neural Network
Regression
The word regression comes from “regression to the mean” like the parent-children height example. Later it actually means using functional form to approximate a bunch of data points.
i.i.d.: Independent and identically distributed, a fundamental assumption for the data.
- Linear Regression
- Polynomial Regression
- Cross Validation
- Split the training set into training and validation set. K-fold cross validation.
- To determine the complexity of the model (degree of polynomial in the case of polynomial regression), choose the complexity with the lowest validation error
Neural Networks
- Perceptron: $ \mathbf{wx} = y $, threshold $ y $ to get $ \hat{y} $
- If linearly separable, it will find a solution
- If not, it won’t stop. But there’s no way to know when to stop and declare it’s not linearly separable.
- Gradient Descent: $ \mathbf{wx} = a $, activation. There’s no thresholding.
- Perceptron vs. Gradient descent
-
Perceptron:
-
Gradient descent:
- Difference: activation with or without thresholding. Gradient descent is more robust, it needs a differentiable loss. The 1-0 loss of perceptron is not differentiable.
- To get a differentiable / softer thresholding function, we have sigmoid (literally means s-like).
-
- Sigmoid unit in NN is just a softer thresholding version of Perceptron.
- Back-propagation for error: computationally beneficial organization of the chain rule.
- Local optima: For a single sigmoid unit, the error looks like a parabola because its quadratic. For many sigmoid units as in NN, there will be a lot of local optima.
- Learning = optimization
- Note that a 1-layer NN with sigmoid activation is equivalent to Logistic Regression!
- NN complexity
- More nodes
- More layers
- Larger weights
- Restriction bias: what it is that you are able to represent, the restriction on possible hypotheses functions
- Started out with Perceptron, linear
- Then more perceptrons for more complex functions
- Then use sigmoids instead of 1-0 hard thresholding
- So NN doesn’t have much restriction. It can represent any boolean function (more units), any continuous function (one hidden layer), and any arbitrary function with discontinuities (more hidden layers).
- Danger of overfitting: use certain network structures, and cross validation.
- Preference bias: given two algorithm representations, why we prefer one over the other
- Initialize weights at small random values
- Always prefer simpler models when the error is similar: Occam’s Razor
- Summary
- Perceptrons: thresholding unit
- Networks can produce any Boolean function.
- Perceptron rule: finite time for linearly separable data
- General differentiable rule - back propagation & gradient descent

What is a salsa dance position
The salsa dance position is a fundamental element of partner dance. Salsa dance elements include the following:
- Steps
- Handholds
- Turns
- Combs
- Stylings
- Positions
- Patterns
- Combinations
A salsa dance position comprises the orientation of the dancers with respect to each other and the handhold. For more about handholds, see this article, which is all about salsa dance handholds.
Aspects of dancer orientation include what direction each dancer is facing, whether the dancers are in a handhold, at what level are the hands held, and the direction of eye gaze.
We refer to the leader as Leader and to the follower as Follower.
Facing Each Other is a common orientation. Here, the dancers are apart and facing each other. Apart means that they are not touching. That also implies that they are not holding hands. That is, they are not in a handhold.
Here is a more advanced position where the dancers are Facing Same Direction, Side By Side, and with Leader On Left.
Why the dance position is important
Salsa dance is a pleasing transition through a series of positions. Every salsa dance pattern begins and ends in a dance position. Expert salsa dancers know how to get into and out of myriad salsa dance positions in interesting ways.
Knowing how to transition through positions in fun and pleasing ways can help increase your salsa dance repertoire. This is facilitated by knowing your dance positions.
How the dance position fits into patterns and combinations
For many salsa dance enthusiasts, salsa dance is the aesthetically pleasing progression through a series of dance combinations over the course of a song. A salsa dance combination is comprised of two or more salsa dance patterns, each pattern covering two bars of music. Every salsa dance pattern begins and ends in a dance position. Therefore, the salsa dance pattern is a pleasing transition from a start position to an end position over eight beats of music. Because salsa dance is made up of combinations, and combinations are made up of patterns, and a dance pattern begins in a position and ends in a position, one can view salsa dance positions as a fundamental building block of the salsa dance combination.
More examples of basic salsa dance positions
Half Closed Position
The dancers are facing each other, with Leader's right hand on Follower's left upper back, and Follower's left hand on Leader's left shoulder.
Open Position
An "open position" is a class of positions where the dancers are not in a closed position, typically in a handhold, and typically facing each other. Because this particular open position is so common it is often referred to simply as *Open Position. The dancers are holding both pairs of hands. This handhold is also referred to as a parallel handhold.
Half Open Right to Left
This is a variation of the Open Position where the dancers are holding only one pair of hands. Leader's right hand is holding Follower's left hand.
Half Open Left to Right
This is another variation of the Open Position where the dancers are holding only one pair of hands. Leader's left hand is holding Follower's right hand.
Handshake
In this position the dancers are facing each other, in a right to right handhold. This is one of those positions that is named after the handhold. However, it is possible to be in an orientation other than the one shown here. See the Salsa Handbooks for examples.
Reverse Handshake
In this position the dancers are facing each other, in a left to left handhold.
Crosshold
This is another position that is named after the handhold. This is a type of open position where the dancers facing each other, holding both pairs of hands, and where the hands are crossed. The handhold is right hand to right hand, left hand to left hand, with Leader's right hand over Leader's left hand.
Here is how this position appears from an overhead view:
Leader can remember this as "left to left, right to right, right over left".
Reverse Crosshold
This is a variation of the Crosshold, where Leader's left hand is over Leader's right hand. Leader can remember it as "left to left, right to right, left over right".
Here is how this handhold appears from an overhead view:
Many positions have inversions which mirror the original position, or where the handhold is inverted. This is why it is helpful to know how to breakdown a position into its parts, so that when introduced to a new position you can realize that it is a variation of a position that you already know.
Crossed Parallel Hold
Here is one of the more unusual positions. It uses a kind of parallel hold but where the hands are crossed. The handhold is left to right and right to left, with Leader's left hand over Leader's right hand.
Note on naming: truthfully there doesn't seem to be a standard name for this handhold. This is one of those handholds where it can be simpler to just explicitly describe the hold, as in "right to left, left to right, left over right". Or, for its inverse variation, as "left to right, right to left, right over left". The section below on Shorthand delves more into this topic.
Here is a closeup view:
Here is how this handhold appears from an overhead view:
You might ask, do people really get into that hold? Is it useful? The answer would be yes, and yes. This handhold can be entered when performing a double handed turn. The variation of this where the hold is inverted (Leader's right hand over Leader's left hand) is obtained when perfoming the double turn in the opposite spin direction.
Applications
A simple handhold in a facing each other orientation can transform into another interesting position just by modifying the orientation of the dancers.
Here is a position involving a right to left, left to right hand hold at high level. This is essentially the same handhold as is used in the standard open position. Only the orientation of the dancers and the height level of the handhold has changed. If you guessed that this position can be obtained by a transition from the Open Position, you would be correct!
Here is a position involving a left to left, right to right handhold, where the dancers are facing the same direction, with Leader in back, and Follower in front.
Here is another application of the left to left, right to right handhold, which we already saw previously above. In this position the dancers are facing the same direction and side by side.
Here is yet another left to left, right to left handhold, where the dancers are facing the same direction and with Leader in front, Follower in back.
Because the last three positions are using the same handhold, you might guess that there is a way to transition from each of these positions to each of the others -- and you would be right. This is one of the fun aspects of salsa dance, figuring out how to enter and exit positions in interesting ways.
Shorthand
There are many other positions not shown here. Many positions do not have commonly accepted names. Because there are so many possible positions it is useful to use a shorthand system for describing positions that do not have common names. It is also useful for providing a standard terminology for introducing common positions that do have a standard name to new dancers who are still just learning the basics. The Salsa Handbooks on which this article is based use a shorthand system for referring to the dancers and their orientation. Those books provide a comprehensive overview of that shorthand notation system. This section gives a brief introduction to a subset of that shorthand notation.
- Facing Each Other (FEO)
- Facing Opposite Directions (FOD)
- Side By Side (SBS)
- Leader In Front (LIF)
- Leader In Back (LIB)
- Leader On Right (LOF)
- Leader On Left (LOL)
- Leader's Left Hand (LLH)
- Leader's Right Hand (LLH)
- Follower's Left Hand (FLH)
- Follower's Right Hand (FLH)
- Right to Right (R to R)
- Left to Left (L to L)
- Left to Right (L to R)
- Right to Left (R to L)
- Leader's right hand over Leader's left hand (LRH/LLH)
- Leader's left hand over Leader's right hand (LRH/LLH)
Imagine all the ways in which you can combine these orientations and handholds. That gives a hint as to the number of possible positions. It turns out that there are many many positions! For a comprehensive compendium of salsa dance positions, see the Handbook of Salsa Dance: Positions, links to which are also given below. Although that handbook is comprehensive, it is still not exhaustive! There are other positions not included there. That is why it is useful to have a system for breaking down a position into consitituent parts. This makes it possible to not only learn novel positions, but to invent new ones.
Here is a position where the dancers are in a handhold, and where the dancers are Facing Same Direction (FSD), Side By Side (SBS), and Leader On Left (LOL). Leader's right hand is to Follower's right hand (Right to Right), and Leader's left hand is to Follower's left hand (Left to Left).
Using the shorthand we can succinctly describe this position as FSD SBS LOL, R to R, L to L.
Summary
All salsa dance patterns begin and end in a dance position. Having this insight makes it easier to assimilate a new dance pattern. A first step in breaking down a dance pattern is to observe how it begins and ends. Understanding the start and end position of a pattern makes it easier to learn the middle part of the pattern.

Decide whether group messages should be deleted automatically in a pre-defined period (in days). Default value is 'On', that means 'Yes'.
However, if you set it 'Off', all messages will be preserved forever until they are deleted manually by message senders (Note: Only message
sender can delete his/her messages).
The length of pre-defined period is control by system setting 'old_msg_delete_days', please refer to section 4.5.5 for details. Please note
this setting can't be changed after message group is created.

| - |
Decide who will be invited to join your message group. Default number of invited member input field is 5, if you have more members to invite, click
button 'More' to add more input fields, or click 'Less' button to remove extra input fields. Please put only one invited member's alias on each input
field.
Note:
Due to security reason, you must know someone's alias to invite him/her to your message group, SMS won't list out available users for you.
|
Then, click 'Create' button to create your message group.
Plese note that:
| - |
Who creates a message group, then he/she will be administrator of that message group, and he/she has full power to do all group administrative
tasks, include delete those message groups which are belongs to him/her. However, his/her administrative power is limited on group level only,
unless he/she is system administrator otherwise.
|
| |
| - |
System administrators have equivalent power of message group administrators on all message groups they belongs to.

An example of basic Slideshow usage. This pages uses nothing more than the slideshow.js
base class and slideshow.css
stylesheet that are included in the download. To customize the slide transitions (for example to create wiping effects) you will want to edit the .slideshow-images-visible
, .slideshow-images-prev
and .slideshow-images-next
classes in the stylesheet. See the next example...


A slide deck is an abstract component that adds a slide effect between components. The height of the slide deck will automatically grow to the next slide. Since each element must be different, or a key must be defined for Vue transitions, the component will automatically add the slide index as a key if a key isn't define. The component handles the differing animations for going backwards and forwards.
A more practical usage would be something inside a popover, there is a login form and the state changes. With each state change, it could transition to a new slide.
You have been logged in!
The controls can be automatically handled with a single property.

I got the anadenanthera seeds becuase it was the cheapest and seemingly most effective source of DMT available. I made the purchase via the internet and recieved the seeds along with some dagga and salvia relativly quickly.
The first thing I tried to do with the seeds was crush them(unroasted) and smoke them with dagga as another person on this site has tried. From this I recieved a numbing in the legs and a pain in the ears that lasted half an hour.
The second thing I did was put a few seeds in the toaster and cooked them until they poped....deshelled them...crushed them...and snorted them. This gave me the worst headache I ever had....and still nothing particulary psychoactive.
ok....so now I became even stupider...
I took five seeds and determined to get some dmt out of them I put them in the toaster for a much longer time period...the result was that I burned them and when deshelled the inside was brown and disgusting smelling. I figured I had ruined them and threw them out but not before eating (yes I ate it!) half a burnt seed. Then I felt I was begining to trip, but it was late so I went to bed. Everything was dancing and running through my mind and I couldn't sleep for at least an hour, at which point my mind was calm and empty.
 Then I crushed them, put them back in the toaster until they were near that burning point, crushed some more....capsulated...and down the hatch! 10 minutes after I got ear pain, morphing objects, dancing colors and lights eminating from everything.
30 minutes in there was PUKEING!  This struck me deep and for some reason the entire yopo experiment seemed worth it then.
I had barfed up what I thought was the entire lot of yopo ingested. Yes I know 'yopo' actually only refers to the snuff made from a relative of the colubrina but this plant has such a long ass name just insert the scientific name in wherever I type 'yopo'. Anyway I thought the trip would end there but I was wrong.
I felt cold and wanted to lie down. I did. But whenever I closed my eyes there were colorful images. Not the usual fun type but fast things that jumped around in brain. So I opened my eyes and real objects seemed to do the same thing buzz rapidly in place. My fan moved and my ceiling would breathe up and down.  I went to the bathroom and found that I didnt flush after barfing (deffinatly not in my right mind) then when I tried to flush it didn't seem to work. These things happen in my house, so instead I went to the one downstairs.
But anyway the light in that bathroom was pretty bright and due to the substance seemingly getting brighter. The floor was glowing and little lights danced through the patterns in the tile. Then a voice in my mind began to repeat 'let there be light'. I relized this world was only visible through reflecting light that reaced our eyes. Then suddenly the world seemed alot stranger...almost unatural...they looked exactly the same as they always looked but I noticed the immensly alien nature of how most normal mundane things looked.
I was still cold and getting colder so I went outside in the sun. As weird as everything in my house looked everything outside looked all the more normal. I laid in the grass in the sun and began to rediscover nature as I had when I was very small.
Back inside the voice came back. I had come looking for answers and I knew that the yopo had buried them within me...the voice told me never to do any psychadellics again as I would never need them again.
The trip lasted 2 hrs on the dot. But now after it I feel completely at peace. I think it was all worth it and I doubt I will never be the same. Deffinately not a recreational drug....IT IS NOT FUN!!! but at the same time it is a serious and worthy teacher.

The driver was stopped on Harvest Home Road in Wollert at about 9.40pm on November 13 when a man approached his door and threw a bag of human faeces at him.
The excrement struck the driver in the face and covered his jacket.
No passengers were hit by the flying faeces.
The offender fled after the filthy attack, and police are calling on the public to help find him.
The attacker was perceived to be Caucasian, aged in his 30s or 40s, of medium height and build, and had a fair complexion.

Investigators have released images of the man in the hope someone may be able to identify him.
Anyone with information on the incident or knows the identity of the man is urged to contact Crime Stoppers on 1800 333 000 or submit a confidential crime report at www.crimestoppersvic.com.au


The MHoC is a model House of Commons, that means that we play politics and pretend to run a country. This test is disigned to help sort people into parties. You will be presented by a statement, and then you will answer with your opinion on the statement, from Strongly Agree to Strongly Disagree, with each answer slightly affecting your scores. At the end of the quiz, your answers will be compared to the maximum possible for each party, thus giving you a percentage. Answer honestly!
There are questions in the test.
There are five independent parties at the moment - Labour, Conservative, Liberal Democrat, Libertarian, and Citizens
Labour
Those in the Labour Party tend to be the most left wing, especially as there is no other left wing party in the MHoC currently.
Conservative
Those in the Conservative Party tend to socially conservative. They tend to support lower taxes, privatization, deregulation.
Liberal Democrat
Those in the Liberal Democrats tend to be socially liberal, although can have authoritarian ways of pushing these policies. They are often to the left of center
Libertarian
Those in the Libertarian are generally classical liberals. They believe in having a small state and want taxes to be as low as possible.
Citizen
Those in the Citizens Party believe in strong civil liberties. They tend to support democracy centerism, taking what they would call a pragmatic approach to politics.

Ronin
As reviewed by James Brundage
OK. Here's a movie about five people with fifty guns and unlimited ammo. Robert de Niro with his pleasant little mole is our friendly neighborhood ex-CIA mercenary. The mathematician from Good Will Hunting is our favorite ex-KGB traitor. The guy from The Professional? He's a nice French mercenary, probably ex-French Secret Service. All of them are killers, all of them darkly comic and all of them after one thing: a nice steel box which has something in it that both the IRA and the Russians want.
It's a movie of one-upsmanship: each scene is better than the last. Each car chase claims more cars, each shootout more lives, each scene, more time. >From the French countryside to the highway tunnels under Paris, Ronin takes you, willing or unwilling, along a complex winding plot of people searching for a mysterious box because of the money… not to mention one or two of them may have an anterior motive.
Somehow, this psychotic inner child has a brain all of its own, coming up with its own plausibility and interesting traits (not to say it would be standard without them… it's one of the finer action films I've ever seen), such as the title itself (a Ronin is a Samurai without a master).  Yeah, come to think of it, it has so much fun shooting this way and that, it makes any action film look like a kid on a scooter… or worse. Some of them are still learning to walk next to this sweet thing.

Security and Listening Devices Tech Issues date posted 04/03/2015 22:03
You've seen it in all the movies, tv shows, and in the news. People being watched by all their beloved electronic devices. Some of my friends even admit to putting black tape over the cameras on their phones, laptops, and even unplugging their webcams. I came across this article in YahooNews. It talks about how any of our home devices could be hacked.
Sometimes when people think about internet security, they think about how people can hack into your bank accounts or emails. But people watching you? It takes stalking to a whole other level. The scariest thing the article points out is that although your house alarm is supposed to keep intruders out, intruders can use it to know if anyone's home.
What's the point of having security if thieves who find out the alarm's on from the outside, know they can walk in, maybe even let the alarm go off, and rush back out? Well, one of the main issues is that people continue to buy convenient technology. For example, when you connect your phone to your TV or to the lights around your house. These luxuries aren't necessarily protected, or at least you wouldn't think they need one. But all someone would have to do is hack into your phone, and they could torment you by turning off and on your lights. Makes you think twice about installing all those apps and new technology. Even baby monitors have been criticized as being unsafe. There's been reports of people finding pictures of their children's cribs online.
So, how are companies trying to remedy the solution? Well, it's extremely difficult. Some companies hire the hackers that hack them. Ironic, right? But it is pretty logical. You want the people that know the flaws of your system to point them out to you and possible fix them. Security systems will slowly become more advanced, however, it is pretty daunting to know that some people can just type in a few lines of code to get access to your personal life.

Document Tampering detection is the task to identify if the digital document image was tampered or not. Previously we looked into various techniques used to identify document tampering.
In the last meeting, we surveyed various datasets on the distribution of the pixel area that was tampered. Also, we looked into the threshold pixel area below which the detection methods completely failed. Please look at the section below for further details.
Work done between: [02/04/19 -> 16/04/19]
We tried to find out the effect of reducing the size of tampering on tampering detection. We show the effect on the current methods used to detect tampering.
In the bar plot above, we show the number of pixels below which each method start to fail. Hence if the area of the patch is smaller than the threshold the particular method fails to detect the tampering. For comparision, generally images contains between about 40000(200x200) to 1048576(1024x1024) pixels.
1. In Yashas' architecture [1], image is converted to 64x64 patches and is checked if it has at least 20% region tampered(which corresponds to about 820 pixels).
2.JPEG artifacts [2] fails when the tampered region is less than 1500 pixels.
3.CMFD [3] fails when the tampered region is less than 3000 pixels.
4.Splicebuster/Noiseprint [4] fail when the tampered region is less than 4096 pixels.
Below we show the distribuition in patch sizes across datasets and whether they contain small tampered regions. We also observe that the payslip dataset has the smallest tampered regions(tampered region of 3 pixels), followed by the CASIA and Find-it challenge(100 or 400 pixels respectively). IEEE dataset has tampering regions larger than 1000 pixels.
Click on the box below to open each dataset
Released in 2013. Contains 451 fake images and 1000 pristine images. Resolution 780x1024.
Contains 5000 fake images and 7000 pristine images. Resolution 256x400.
The dataset is released by Mickaël Coustaty, University of La Rochelle,France. It was released as an ICPR challenge in 2018. Contains 200 fake images and 1800 pristine images. Resolution varying image sizes in HD resolution. Report on challenge
The dataset is released by Mickaël Coustaty, University of La Rochelle,France. The dataset contains 3 types of tampering. Copy Paste Intra, Copy Paste Inter & Imitation.

Installation
You can either download one of the pre-built binaries or build the source code manually. Executables for Windows and Mac and other resources can be downloaded from https://demuc.de/colmap/. Executables for Linux/Unix/BSD are available at https://repology.org/metapackage/colmap/versions. Note that the COLMAP packages in the default repositories for Linux/Unix/BSD do not come with CUDA support, which requires manual compilation but is relatively easy on these platforms.
COLMAP can be used as an independent application through the command-line or graphical user interface. Alternatively, COLMAP is also built as a reusable library, i.e., you can include and link COLMAP against your own source code, as described further below.
Pre-built Binaries
Windows
For convenience, the pre-built binaries for Windows contain both the graphical
and command-line interface executables. To start the COLMAP GUI, you can simply
double-click the COLMAP.bat
batch script or alternatively run it from the
Windows command shell or Powershell. The command-line interface is also
accessible through this batch script, which automatically sets the necessary
library paths. To list the available COLMAP commands, run COLMAP.bat -h
in
the command shell cmd.exe
or in Powershell.
Mac
The pre-built application package for Mac contains both the GUI and command-line
version of COLMAP. To open the GUI, simply open the application and note that
COLMAP is shipped as an unsigned application, i.e., when your first open the
application, you have to right-click the application and select Open and then
accept to trust the application. In the future, you can then simply double-click
the application to open COLMAP. The command-line interface is accessible by
running the packaged binary COLMAP.app/Contents/MacOS/colmap
. To list the
available COLMAP commands, run COLMAP.app/Contents/MacOS/colmap -h
.
Build from Source
COLMAP builds on all major platforms (Linux, Mac, Windows) with little effort. First, checkout the latest source code:
git clone https://github.com/colmap/colmap
On Linux and Mac it is generally recommended to follow the installation instructions below, which use the system package managers to install the required dependencies. Alternatively, there is a Python build script that builds COLMAP and its dependencies locally. This script is useful under Windows and on a (cluster) system if you do not have root access under Linux or Mac.
 -GNinja
ninja
sudo ninja install
Run COLMAP:
colmap -h
colmap gui
To compile with CUDA support, also install Ubuntu’s default CUDA package:
sudo apt-get install -y \
nvidia-cuda-toolkit \
nvidia-cuda-toolkit-gcc
Or, manually install latest CUDA from NVIDIA’s homepage. During CMake configuration specify CMAKE_CUDA_ARCHITECTURES as “native”, if you want to run COLMAP on your current machine only, “all”/”all-major” to be able to distribute to other machines, or a specific CUDA architecture like “75”, etc.
Under Ubuntu 16.04/18.04, the CMake configuration scripts of CGAL are broken and you must also install the CGAL Qt5 package:
sudo apt-get install libcgal-qt5-dev
Under Ubuntu 22.04, there is a problem when compiling with Ubuntu’s default CUDA package and GCC, and you must compile against GCC 10:
sudo apt-get install gcc-10 g++-10
export CC=/usr/bin/gcc-10
export CXX=/usr/bin/g++-10
export CUDAHOSTCXX=/usr/bin/g++-10
# ... and then run CMake against COLMAP's sources.
 -DQt5_DIR=/opt/homebrew/opt/qt@5/lib/cmake/Qt5
make
sudo make install
If you have Qt 6 installed on your system as well, you might have to temporarily link your Qt 5 installation while configuring CMake:
brew link qt5
cmake configuration (from previous code block)
brew unlink qt5
Run COLMAP:
colmap -h
colmap gui
Windows
Recommended dependencies: CUDA (at least version 7.X), Visual Studio 2019
On Windows, the recommended way is to build COLMAP using vcpkg:
git clone https://github.com/microsoft/vcpkg
cd vcpkg
.\bootstrap-vcpkg.bat
.\vcpkg install colmap[cuda,tests]:x64-windows
To compile CUDA for multiple compute architectures, please use:
.\vcpkg install colmap[cuda-redist]:x64-windows
Please refer to the next section for more details.
Visual Studio 2022 has some known compiler bugs that crash when compiling COLMAP’s source code.
VCPKG
COLMAP ships as part of the vcpkg distribution. This enables to conveniently build COLMAP and all of its dependencies from scratch under different platforms. Note that VCPKG requires you to install CUDA manually in the standard way on your platform. To compile COLMAP using VCPKG, you run:
git clone https://github.com/microsoft/vcpkg
cd vcpkg
./bootstrap-vcpkg.sh
./vcpkg install colmap:x64-linux
VCPKG ships with support for various other platforms (e.g., x64-osx, x64-windows, etc.). To compile with CUDA support and to build all tests:
./vcpkg install colmap[cuda,tests]:x64-linux
The above commands will build the latest release version of COLMAP. To compile the latest commit in the dev branch, you can use the following options:
./vcpkg install colmap:x64-linux --head
To modify the source code, you can further add --editable --no-downloads
.
Or, if you want to build from another folder and use the dependencies from
vcpkg, first run ./vcpkg integrate install and then configure COLMAP as:
cd path/to/colmap
mkdir build
cd build
cmake .. -DCMAKE_TOOLCHAIN_FILE=path/to/vcpkg/scripts/buildsystems/vcpkg.cmake
cmake --build . --config release --target colmap_exe --parallel 24
Alternatively, you can also use the Python build script. Please follow the instructions in the next section, but VCPKG is now the recommended approach.
Build Script
Alternative to the above solutions, COLMAP also ships with an automated Python build script. Note that VCPKG is the preferred way to achieve the same now. The build script installs COLMAP and its dependencies locally under Windows, Mac, and Linux. Note that under Mac and Linux, it is usually easier and faster to use the available package managers for the dependencies (see above). However, if you are on a (cluster) system without root access, this script might be useful. This script downloads the necessary dependencies automatically from the Internet. It assumes that CMake, Boost, Qt5, CUDA (optional), and CGAL (optional) are already installed on the system. E.g., under Windows you must specify the location of these libraries similar to this:
python scripts/python/build.py \
--build_path path/to/colmap/build \
--colmap_path path/to/colmap \
--boost_path "C:/local/boost_1_64_0/lib64-msvc-14.0" \
--qt_path "C:/Qt/5.9.3/msvc2015_64" \
--cuda_path "C:/Program Files/NVIDIA GPU Computing Toolkit/CUDA/v8.0" \
--cgal_path "C:/dev/CGAL-4.11.2/build"
Note that under Windows you must use forward slashes for specifying the paths
here. If you want to compile COLMAP using a specific Visual Studio version, you
can for example specify --cmake_generator "Visual Studio 14"
for Visual
Studio 2015. If you want to open the COLMAP source code in Visual Studio, you
can open the solution file in path/to/colmap/build/colmap/build
.
If you use Homebrew under Mac, you can use the following command:
python scripts/python/build.py \
--build_path path/to/colmap/build \
--colmap_path path/to/colmap \
--qt_path /usr/local/opt/qt
To see the full list of command-line options, pass the --help
argument.
Library
If you want to include and link COLMAP against your own library, the easiest way
is to use CMake as a build configuration tool. After configuring the COLMAP
build and running ninja/make install, COLMAP automatically installs all
headers to ${CMAKE_INSTALL_PREFIX}/include/colmap
, all libraries to
${CMAKE_INSTALL_PREFIX}/lib/colmap
, and the CMake configuration to
${CMAKE_INSTALL_PREFIX}/share/colmap
.
For example, compiling your own source code against COLMAP is as simple as
using the following CMakeLists.txt
:
cmake_minimum_required(VERSION 3.10)
project(SampleProject)
find_package(colmap REQUIRED)
# or to require a specific version: find_package(colmap 3.4 REQUIRED)
add_executable(hello_world hello_world.cc)
target_link_libraries(hello_world colmap::colmap)
with the source code hello_world.cc
:
#include <cstdlib>
#include <iostream>
#include <colmap/controllers/option_manager.h>
#include <colmap/util/string.h>
int main(int argc, char** argv) {
colmap::InitializeGlog(argv);
std::string message;
colmap::OptionManager options;
options.AddRequiredOption("message", &message);
options.Parse(argc, argv);
std::cout << colmap::StringPrintf("Hello %s!", message.c_str()) << std::endl;
return EXIT_SUCCESS;
}
Then compile and run your code as:
mkdir build
cd build
export colmap_DIR=${CMAKE_INSTALL_PREFIX}/share/colmap
cmake .. -GNinja
ninja
./hello_world --message "world"
The sources of this example are stored under doc/sample-project
.
AddressSanitizer
If you want to build COLMAP with address sanitizer flags enabled, you need to use a recent compiler with ASan support. For example, you can manually install a recent clang version on your Ubuntu machine and invoke CMake as follows:
CC=/usr/bin/clang CXX=/usr/bin/clang++ cmake .. \
-DASAN_ENABLED=ON \
-DTESTS_ENABLED=ON \
-DCMAKE_BUILD_TYPE=RelWithDebInfo
Note that it is generally useful to combine ASan with debug symbols to get meaningful traces for reported issues.
Documentation
You need Python and Sphinx to build the HTML documentation:
cd path/to/colmap/doc
sudo apt-get install python
pip install sphinx
make html
open _build/html/index.html
Alternatively, you can build the documentation as PDF, EPUB, etc.:
make latexpdf
open _build/pdf/COLMAP.pdf

The age-old question: should I make a closed board or should I directly challenge both of my opponent’s outer board points?
The answer is very clear – make the closed board with 16/5.
The problem with 21/16, 12/6 is that a parlay is required to win – hit a shot and then contain the hit blot. After 16/5 any hit blot is automatically contained by the fully closed board. 21/16, 12/6 is not quite a blunder but is very close.

Go Code for SQL DAL Generation
James Culbertson, Houston Golang Meetup, October 18, 2018
SQL Database Access Options
- Manual Coding of Database Access
- Extender Libraries and Query Builders
- Object-Relational Mappers (ORM) Libraries
- Data Access Layer (DAL) Generators
Manual Coding of Database Access
- Built on interfaces provided by the standard "database/sql" package along with the DB-specific client driver
Pros
- Efficient code at runtime
- High level of control and flexibility of the implementation
Cons
- Lots of manual boilerplate code to write
- Must manually write a lot of SQL code
- Can be prone to security issues
Manual Coding Example
Extenders and Query Builder Libraries
- Extends "database/sql" to provide higher-level abstractions and tools to make data access easier
- Can build SQL queries from composable parts
Pros
- Higher level of control and flexibility of the implementation
- Less boilerplate
- Abstracts out some of the database-specific quirks
Cons
- Must manually write the SQL code (extenders)
- Some performance penalty on packages that use reflection (query builders)
Extenders/Query Builders Examples
ORM Libraries
- Provides a "code-first" approach to developing data access
- Some provide automatic migration
Pros
- Easier to Use
- No boilerplate code
- Abstracts the database type
Cons
- Less Control of the Implementation
- Biggest performance penalty of the various options
ORM Example
DAL Generators
- Provides a "database-first" approach to developing data access
- Generates models and database access code
Pros
- Easy to Use
- Boiler plate code automatically generated
- Templates can extend and customize generated code
- As performant as manually-generated code
Cons
- Less Active Support on the Github Repositories
DAL Generator Example
How DAL Generators Work
- The dev or DBA creates the application database.
- The dev initiates generation from the CLI with the database connection URL and other arguments.
- The generator analyzes the schema of the database.
- The generator loads an internal model of the schema.
- The generator uses pre-packaged and/or user-provided templates to generate the models and data access code.
Using the Generator
Simple Case
$ mkdir models
$ xo postgres://user:pass@host/dbname -o models
Custom Templates With Verbose Mode
$ mkdir sqliteModels
$ xo sqlite3://dbname.db -v -o sqliteModels --template-path /custom/templates/
Many other command line options are available.
Using the Generated Code
- Import the generated code to use the models and call the data access methods.
- Repeat the generation when the database schema or templates have changed.
Template Example
gendal
- Fork of xo to provide support on PR's and issues
- Adds support for CockroachDB
- Packages are now versioned with dep
- Releases are formalized and tagged
